ADOLPH KURTZ, OF SAN FRANCISCO, CALIFORNIA.

LlQUl D-COOLER.

SPECIFICATION forming part of Letters Patent No. 325,418, :iated September 1, 1885.

Application filed July 523, 1883.

To all whom it may concern.-

Be it known that I, ADOLIII Kun'rz, a citizen of the United States, residing in the city and county of San Francisco, and State of California, have invented a new and useful Improvement in Liquid-Coolers, of which the following is a specification.

My invention relates to improvements in liquidcoolers, in which the beer or other liquid holder is surrounded by an icechan1ber, which is in turn surrounded with a non-eonductingjacket or outside chamber filled with charcoal or other suitable non conducting substance.

My invention will be more fully understood by reference to the accompanying drawings, in which Figure 1 is a section cut vertically through the center; Fig. 2, a plan View, and Fig. 3 a perspective View showing the cooler connected with the beer-barrel.

The following is the construction of the same: I form the beer or liquid holder A, of any convenient size, of strong sheet metal, or crockery or other suitable material, with a tight-fitting lid, 13, to screw in and make an air-tight fit by any suitable packing. In this lid I construct the opening G, which I also close with a screw cap or pla D. I also form the vent E to regulate the escape of gas. 1.

I line this lid with a non-conducting substance. Surronnding this chamber A, I form the ice space or chamber F, sufficient] y broad to receive the necessary amount of ice for cooling the beer. I form the same with noncouducting covers, made so by lining with charcoal or other non-conducting material. Around next to the outside and under the whole of the beer-holder and icechamber I form the jacket or non-conducting space J, which I till with charcoal or other suitable non-conducting material, packing the same tightly and permanently. I place the faucet G in the beer-cooler A and extend it through the ice-chamber F and out through the outer jacket, J, and the faucet H, I extend from the ice-chan1ber F, through the jacket J, to draw off the water which accumulates from (No model.)

the melting ice. I connect the cooler A with the beer-barrel by means of the pipe or hose 1?. (Shown in Figs. 1 and 3.)

The following is the operation of the same: I open the faucet in the beer-barrel and the beer flows through the pipe 1? into the cooler A, the vent E being open to allow the airnn the same to escape and let the beer fiow 1n. Vhen the chamber A is filled, it is quickly cooled by the ice in the ice-chamber F, and the outer j aeket, J, prevents the ice from melting by the action of external heat; but as the ice is melted by the heat that radiates from the beer, the water is drawn off through the faucet II. The chamber or cooler A is then closed tightly, and the beer may be drawn off freely through the faucet G. The flow may be regulated by opening or closing the faucet M leading from the beenbarrel, as there is always a pressure in the barrel from the gas of the beer. The beer being drawn from the bottom is kept constantly cool, as the warm beer, fresh from the barrel, being of less gravity, stays at the top,of the chamber A, having plenty of time to cool as it is slowly drawn down by the cool beer being drawn out at the bottom.

Having thus described my invention, what I claim, and desire to secure by Letters Patent,

The beer'cooler' described, comprising the chamber A, for containing the beer, a chamber, F, surrounding the same, and adapted to contain ice, aspace or chamber, J, between the chamber F and outer side of the tank, a filling of non-conducting material-such as charcoal-in space J, a pipe leading from the beer-chamber A through the iccchamber, a vent E, removable cover for the ice-ehamber, a cover, B, having a threaded opening, an exteriorly-threaded plug to engage the same, and a pipe fitting said plug, substantially as set forth.
